Southstone Rock was a 7 retreat for hermits and pilgrims who travelled here to take the Tufa deposit waters from a holy well.in Norman times a chapel dedicated to Site of modern or active St John the Baptist stood on top of the rock. It is said that two tufa formation monks from the Abbey of Evesham were located here as 4 Location guardians of the chapel. Offerings were made to the chapel at the feast of St John the Baptist at a service ending with the drinking of water from the holy well.

This coating is called Travertine.

The southern end of this road is met by the B2404 which runs from Martley to Tenbury Wells. The closest public transport is at Clifton upon Teme.
